Definitions

  • the invention patent refers to a device for fixing plates on a table, especially for pantograph-type equipment that has two X and Y axes.
  • the method of cutting can be laser, water jet, milling cutter, etc. and applications can be signage, signage, facades, etc.
  • the material does not move and in engraving work (those that do not involve cutting), it is essential that the distance of the tool to the plate remains constant.
  • the problem to be solved is to have an ironing device that is fast acting, valid for any format and size of the plate, applicable to different thicknesses and materials, that achieves a homogeneous support, with a reduced cost and without maintenance .
  • the proposed fixing device solves all the problems described above, for this purpose one or more fixed treadmills are applied on one of the edges of the plate and by pressure they prevent the movement of the plate. On the other hand there is one or several rollers mounted on the shaft that travels over the plate and press the plate along its entire length.
  • rollers are mounted on a pivoting element with a bracket configuration, so that it is possible to save edges, grooves, obstacles, etc. with a minimum of drag effort, not overloading the shaft drive on which they are mounted.
  • This overhang has springs that press the rollers against the plate.
  • the proposed device has a plate fixing device for its perimeter area that is made up of auxiliary rollers that, actuated by means of a lever, press on the plate while retaining it.
  • a lever is actuated which it pushes a guide that has several support points defined by pivots which are integral with a lever articulated in its central part by means of a tilting joint and whose auxiliary roller is disposed at its upper end.
  • auxiliary rollers can be arranged as necessary along the table.
  • Figure 1.- Shows a perspective view of the fixing device object of the present invention.
  • Figure 2. Shows a detailed view of the fastening means.
  • FIG. 3 Shows a detailed view of the rollers of the device of the invention.
  • the fixing device (1) comprises:
  • said springs (14) push an arm (11) that is articulated on an axis (3) on which said arm (11) pivots with respect to a support (12).
  • the clamping means (15) move along the table (17) in such a way that they are exerting pressure and thus holding the plate (20) to be machined.
  • the device (1) has auxiliary clamping means (3) arranged along a side face of the table (17) and having a control bar (6 ) that runs along said lateral face and that is fixed thereto by means of anchors (9) that are inserted in holes drilled in said control bar (6), holes that can be round or in the form of a curved collision allowing the displacement of the control bar (6) in the longitudinal direction.
  • Said anchors (9) can have drag pivots (8) that are responsible for preventing the exit of a lever (5), which has vertical oblong to be dragged by the pivots of drag (8), at the end of which is a hole through which the pivot (9) is inserted, said lever (5) in turn has a pivot joint (10), which joins a guide (16) and on it pivot the levers (5) in its central part and of an auxiliary roller (4) disposed at its free end, so that when the control bar (6) is operated by pushing a drive lever (7) integral with said control bar (6) by means of an articulated mechanism, the control bar (6) pushes the lever (5) that rotates on the pivoting joint (10) by moving the auxiliary roller (4) describing an arc of circumference until contacting the plate (20) exerting pressure on it, thus attaching it to the table (17). This is achieved since the pivot joint (10) is fixed to the guide (16) so that the levers (5) pivot on the pivot joint (10).
  • the guide (16) has areas higher than the support table (17), so that they serve as lateral support to maintain the alignment of the plates (20) to be machined.
